obama. michael, good to see you. >> good morning, matt. >> he's under federal custody right now. he's not been mirandized. hasn't been read the lights we see in tv and in the movies and a normal part of criminal proceedings. what leeway does that give the federal government and what does it not allow them to do? >> the federal government has a fair bit of latitude at the beginning to ask him questions that relate to directly to the public safety about other bombs, about other plotters. now, this is all judicial doctrine so there's no clear standards on how long that would last but that period should go into today and maybe even tomorrow. at some point he's going to have to be presented to a u.s. magistrate and hear the charges and from there he'll get back into the system. the hope would be that he'll talk even if he is mirandized by the fbi. >> so this public safety exception, are there other bombs out there, other accomplices, is it going to take a smart defense lawyer to say, wait a secon
